Sources say Sony's thinking about selling off their Cell CPU manufacturing plants, as evidenced by their recent canoodling with Toshiba. These plants would be the same ones where Sony currently produces the processos used in the PS3—you know, the Cell processors. If true, this sale would help Sony free up $860 million in free cash and allow them to focus their efforts on other parts of the company like their digital camera and HDTV divisions where they're not doing so poorly.
